Biden has recently admitted that all living past presidents have been in contact with him, apart from one.
And I think we all know who that is. Keep scrolling for Biden's full, revealing interview...
Joe Biden revealed on Tuesday he's talked to all the previous presidents with the exception of one...
And also admitted that he'd never actually been in the White House residence before - even as vice president.
Here's the full story...
Now, Biden has thrown himself into his new role with gusto.
Just one month after his move to the White House, the newly-elected president has been busy dismantling a whole array of controversial Trump-era regulations.
Mere hours after his inauguration ceremony, Biden fulfilled one of his top campaign promises by pledging to put the U.S. back in the Paris Agreement on climate change - an international pact aimed at curbing emissions that cause global warming.
Trump famously withdrew from the agreement in 2017, citing costs to American taxpayers.
And as for the country's ongoing racial division?
Well, Biden has already got to work on putting the pieces back together.
He first signed an executive order to promote racial equity.
Biden ordered his government to conduct equity assessments of its agencies and reallocate resources to "advance equity for all, including people of color and others who have been historically underserved, marginalized and adversely affected by persistent poverty and inequality."
He then reversed Trump's infamous ban on U.S. entry from majority-Muslim countries.
Biden's proclamation reversed Trump's policy that barred entry to the U.S. for refugees and residents from 7 predominantly Muslim countries and orders plans within forty-five days for resuming visa processing.
He also reversed the decision to ban the trans community from serving in the military.
The controversial decision was initially passed by the Trump administration, but has since been reversed as soon as Biden came into power.
He has even brought back the plans for the face of Harriet Tubman to be put on the new $20 bill design.
This plan was originally proposed by the Obama administration but was then promptly stalled upon Trump's entry to the White House.
In a Monday press briefing, White House Press Secretary, Jen Psaki said:
"It's important that our notes, our money... Reflect the history and diversity of our country, and Harriet Tubman's image gracing the new $20 note would certainly reflect that."
She added that the administration is "exploring ways to speed up that effort, but any specifics would, of course, come from the Department of Treasury."
And, on top of all that...
He has also been clamping down on the country's COVID-19 response.
Biden signed an executive order which created the position of COVID-19 response coordinator, who will advise the president and oversee the distribution of vaccines, tests, and other supplies.
An executive order requiring mask-wearing on federal property was also signed.
Despite all this, it appears one past POTUS hasn't been in touch since Biden stepped in office...
Biden revealed the details about his first month as president during an interview with CNN.
He spoke about the weight he feels being president before CNN's Anderson Cooper asked him the big question...
"Have you picked up the phone and called any former president yet?""Yes, I have," Biden confirmed.
"'Do you want to say who?" Anderson responded.
Biden didn't say who, but noted all but one living president has reached out to him.
"They're private conversations," Biden said. "But, by the way, all of them have with one exception picked up the phone to call me as well."
Biden didn't reveal who hasn't called him but it seems pretty clear who it was.
And he seemed pretty fed up with all the Trump questions...
"For 4 years, all that's been in the news is Trump," he said.
"The next 4 years, I want to make sure all the news is the American people. I'm tired of talking about Trump," he continued.
Biden went on to say despite only being 4 weeks in office, it feels like 4 years already.
"It's not because of the burden is because there's so much happening that you focus on, you're constantly focusing on one problem or opportunity," he said.
He also revealed that, despite working as VP for 8 years, he never once set foot in the White House residence...
"I had never been up in the residence," Biden noted. Which is shocking considering the bond Biden and Obama share.
Cooper interrupted to follow up, "Wait you had never been in the residence of the White House?" he asked.
"I have only been upstairs in the, in the yellow room, you know, that the oval upstairs," Biden said, referring to the private living room on the second floor.
We're totally shocked!
